Feeding Habits of Northeast Atlantic Harp Seals ( Phoca groenlandica) along the Summer Ice Edge of the Barents Sea

Stomachs from 58 harp seals (Phoca groenlandica) from the northern part of the Barents Sea were collected between August 20 and September 5, 1987. Fifty-six of the stomachs contained identifiable remains. The amphipod Parathemisto libellula was the most common food item, found in 98% of the seal sto...

Decapods, mainly Pandalus borealis, were also common as prey of harp seals. No sex- or age-related differences in choice of food were found.
